That's a good question. I don't recall any step by step posts on how to build a community. I will check though. Have a look at @stephenkendal.

Basically you need a monthly meetup, a community leader, an event organizer, social media manager, which includes steemit, and a Steemit account. Once you have those it should grow organically.

A friend of mine, @ackhoo is in Malaysia, but maybe up in Kuala Lampur. I'm not sure about the Malaysian/Singapore relationship, but you may want to reach out to her for more members.

Let me know if there is anything I can do to help you.
